Description
Technical Field
The invention relates to the technical field of metallurgical equipment, in particular to a full-drive 4SPeS + SPS + C type parallel plate strip rolling mill with upper and lower rollers.
Background
A rolling mill is main equipment for processing cold-rolled strips, and plate shape control is one of core control technologies. In recent years, advanced cold-rolled strip rolling mills and corresponding strip shape control technologies are emerging and perfected day by day. The development of the plate shape control technology promotes the equipment progress and the industrial upgrading of the cold-rolled plate strip industry, and the production efficiency and the benefit are greatly improved.
The plate shape refers to the warping degree of the plate strip, and the distribution of residual stress in the reaction plate strip. Excessive residual stress can cause instability of the plate strip and warping. In order to obtain high-quality rolled strips, the roll gap of the rolls must be adjusted at any time to adapt to the incoming sheet crown and to compensate for the influence of various factors on the roll gap. The essence of strip shape control is the control of the load roll gap, which must control the full roll gap shape over the span of the width of the product. The conventional plate shape control means mainly comprise a roll bending control technology, a roll tilting control technology, a sectional cooling control technology and the like. In recent years, some special control techniques: advanced strip shape control technologies such as roll drawing, roll cross strip shape control, roll expansion, roll force distribution control, roll edge thermal spraying and the like are increasingly widely applied. The roll drawing technology is also called HC rolling mill roll transverse moving plate shape control system, HC is high performance roll convexity. The technical rolling mill is based on a common 4-roll rolling mill, a pair of axially movable intermediate rolls is arranged between a supporting roll and a working roll, and the rolling plate shape control capability is improved. The control technology of the cross plate shape of the roller of the rolling mill realizes the control of the shape of the roller gap by adjusting the cross angle of the roller to ensure that the roller gap is larger at the position farther away from the center of the roller. Patent CN1171690B discloses a method and a device for controlling plate shape in plate rolling process, which corrects the crossing angle of the rolls and the operation amount of the roll pre-bending force variation mechanism. Patent CN1131740B provides a coil rolling method in which work rolls having tapered rolls at one end are moved in the axial direction, and upper and lower rolls are crossed, wherein the work rolls are crossed at the obtained crossing angle by obtaining the amount of operation for correcting the thinning of the edge of the coil such as the movement amount and the crossing angle, so that the thickness of the entire coil in the width direction can be made uniform during rolling.
The existing rolling mill equipment comprises: the control on the local thickening of the edge of the hot-rolled strip steel is realized by optimizing the original roll profile curve of the working roll of the finishing mill group; the online cross adjustment is realized through the online cross mechanism of the rollers of the PC rolling mill; a working roll profile curve is designed, the crossing angle and the roll bending force are reduced, and the stability of the rolling mill and the plate convexity control capability of the PC rolling mill are improved. However, the structure of installing a pair of axially movable intermediate rollers between the supporting roller and the working roller is complicated; the existing roller cross plate shape control technology has the defects of complex structure and high control difficulty. Therefore, how to simplify the structure and control process of the rolling mill equipment on the premise of improving and enhancing the strip shape control level is always the effort of mechanism designers. In view of the foregoing, there is a need for a new rolling mill that solves the deficiencies of the prior art.
